1 usage: valgrind [options] prog-and-args 2 3 tool-selection option, with default in [ ]: 4 --tool=<name> use the Valgrind tool named <name> [memcheck] 5 6 basic user options for all Valgrind tools, with defaults in [ ]: 7 -h --help show this message 8 --help-debug show this message, plus debugging options 9 --version show version 10 -q --quiet run silently; only print error msgs 11 -v --verbose be more verbose -- show misc extra info 12 --trace-children=no|yes Valgrind-ise child processes (follow execve)? [no] 13 --trace-children-skip=patt1,patt2,... specifies a list of executables 14 that --trace-children=yes should not trace into 15 --trace-children-skip-by-arg=patt1,patt2,... same as --trace-children-skip= 16 but check the argv[] entries for children, rather 17 than the exe name, to make a follow/no-follow decision 18 --child-silent-after-fork=no|yes omit child output between fork & exec? [no] 19 --vgdb=no|yes|full activate gdbserver? [yes] 20 full is slower but provides precise watchpoint/step 21 --vgdb-error=<number> invoke gdbserver after <number> errors [999999999] 22 to get started quickly, use --vgdb-error=0 23 and follow the on-screen directions 24 --track-fds=no|yes track open file descriptors? [no] 25 --time-stamp=no|yes add timestamps to log messages? [no] 26 --log-fd=<number> log messages to file descriptor [2=stderr] 27 --log-file=<file> log messages to <file> 28 --log-socket=ipaddr:port log messages to socket ipaddr:port 29 30 user options for Valgrind tools that report errors: 31 --xml=yes emit error output in XML (some tools only) 32 --xml-fd=<number> XML output to file descriptor 33 --xml-file=<file> XML output to <file> 34 --xml-socket=ipaddr:port XML output to socket ipaddr:port 35 --xml-user-comment=STR copy STR verbatim into XML output 36 --demangle=no|yes automatically demangle C++ names?

[yes] 39 --error-exitcode=<number> exit code to return if errors found [0=disable] 40 --show-below-main=no|yes continue stack traces below main() [no] 41 --suppressions=<filename> suppress errors described in <filename> 42 --gen-suppressions=no|yes|all print suppressions for errors? [no] 43 --db-attach=no|yes start debugger when errors detected? [no] 44 --db-command=<command> command to start debugger [... -nw %f %p] 45 --input-fd=<number> file descriptor for input [0=stdin] 46 --dsymutil=no|yes run dsymutil on Mac OS X when helpful? [no] 47 --max-stackframe=<number> assume stack switch for SP changes larger 48 than <number> bytes [2000000] 49 --main-stacksize=<number> set size of main thread's stack (in bytes) 50 [use current 'ulimit' value] 51 52 user options for Valgrind tools that replace malloc: 53 --alignment=<number> set minimum alignment of heap allocations [not used by this tool] 54 --redzone-size=<number> set minimum size of redzones added before/after 55 heap blocks (in bytes). [not used by this tool] 56 57 uncommon user options for all Valgrind tools: 58 --fullpath-after= (with nothing after the '=') 59 show full source paths in call stacks 60 --fullpath-after=string like --fullpath-after=, but only show the 61 part of the path after 'string'. Allows removal 62 of path prefixes. Use this flag multiple times 63 to specify a set of prefixes to remove. 64 --smc-check=none|stack|all|all-non-file [stack] 65 checks for self-modifying code: none, only for 66 code found in stacks, for all code, or for all 67 code except that from file-backed mappings 68 --read-var-info=yes|no read debug info on stack and global variables 69 and use it to print better error messages in 70 tools that make use of it (Memcheck, Helgrind, 71 DRD) [no] 72 --vgdb-poll=<number> gdbserver poll max every <number> basic blocks [5000] 73 --vgdb-shadow-registers=no|yes let gdb see the shadow registers [no] 74 --vgdb-prefix=<prefix> prefix for vgdb FIFOs [/tmp/vgdb-pipe] 75 --run-libc-freeres=no|yes free up glibc memory at exit on Linux? [yes] 76 --sim-hints=hint1,hint2,... known hints: 77 lax-ioctls, enable-outer, fuse-compatible [none] 78 --fair-sched=no|yes|try schedule threads fairly on multicore systems [no] 79 --kernel-variant=variant1,variant2,... known variants: bproc [none] 80 handle non-standard kernel variants 81 --show-emwarns=no|yes show warnings about emulation limits? [no] 82 --require-text-symbol=:sonamepattern:symbolpattern abort run if the 83 stated shared object doesn't have the stated 84 text symbol. Patterns can contain ? and *. 85 --soname-synonyms=syn1=pattern1,syn2=pattern2,... synonym soname 86 specify patterns for function wrapping or replacement. 87 To use a non-libc malloc library that is 88 in the main exe: --soname-synonyms=somalloc=NONE 89 in libxyzzy.so: --soname-synonyms=somalloc=libxyzzy.so 90 91 user options for Nulgrind: 92 (none) 93 94 Extra options read from ~/.valgrindrc, $VALGRIND_OPTS, ./.valgrindrc 95 96 Nulgrind is Copyright (C) 2002-2012, and GNU GPL'd, by Nicholas Nethercote. 97 Valgrind is Copyright (C) 2000-2012, and GNU GPL'd, by Julian Seward et al. 98 LibVEX is Copyright (C) 2004-2012, and GNU GPL'd, by OpenWorks LLP et al. 99 100 Bug reports, feedback, admiration, abuse, etc, to: www.valgrind.org. 101 102
